I am trying to find if a direct route exists in camel with the help of a try catch block like below. I am looking for a predicate to check if a route exists in camel or not. I could not find anything that directly gives me the answer, so I took the below approach,

<doTry>
<recipientList>
<description>Check if a country specific handler is available</description>
<simple>direct:${header.operationName}${body.country}</simple>
</recipientList>
<doCatch>
<exception>org.apache.camel.component.direct.DirectConsumerNotAvailableException</exception>
<recipientList>
<description>if a country specific handler is not available to to the base</description>
<simple>direct:${header.operationName}</simple>
</recipientList>
</doCatch>
</doTry>

This means that I am forced to use the exception handler in camel to catch a DirectConsumerNotAvailableException to determine if a route exists. I am looking at an alternate approach where we can use a simple expression like exists below,
